COMBINED-"REGISTER AND VENTILAT QR.

, SPECIFICATION forming part of Letters Patent No. 290,084, datedDecember 11, 1883. Application filed March 13, 1883. (Modehl To all whomit may concern:

Be it known that I, WILLIAM H. MAXEIELD, of Maysville, in the county ofAllen and State of Indiana, have invented certain new and usefulImprovements in a Combined Register and Ventilator, of which thefollowing is a full, clear, and exact description.

This invention consists in certain constructions and combinations ofparts in a ventilator, or combined register and ventilatonfor use eitherin ceilings or elsewhere, whereby, while the whole is made to present anornamental appearance, increased facility is afforded for removing andcleaning the interior or working parts of the device, and for operatingit from opposite ends of its air-box, substantially as hereinafterdescribed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inboth the figures.

Figure 1 represents avertical section of my improved register andventilator applied to connect the ceiling of one room with the floor ofa room above, and Fig. 2 a plan of the same.

Referring to the drawings, A indicates the ceiling of one room, and Bthe floor of a room immediately above it. 0 is one of the joistssupporting said floor.

D is the air-box of the device, of oblong or oval form in its horizontalsection to provide for giving it an increased capacity, and at the sametime arrange for its insertion between the joists when close to oneanother. This box extends down below the ceiling A and up to or aboutthe level of the floor B. Its lower end is inclosed within a molding, E,which underlaps the plastering of the ceiling A for some distance allaround the opening for the box in said ceiling, and forms an ornamentalcenter-piece when the device is arranged to occupy a central positionrelatively to the rooms. The upper end-of said box is entered within asocket-piece on the under side of a perforated register plate or'top, F,arranged to extend beyond the opening in the floor and receiving thecarpet I) of the floor beneath it. Said top may be fastened to the floorby screws 0, which, on being taken out, admit of the register plate ortop being raised and removed to get at the internal or working parts ofthe device, that may then be taken out and cleaned or dusted. Theair-box D is entered to its place from beneath and afterward the moldingE fitted around and beneath the same to support it, and fastened byscrews to the ceiling A or joists G, which carry the floor B. 1

G is the perforated plate or grate in the bottom of the box D, on orover which the slotted slide or regulating-valve H works to open more orless or wholly close the openings in the grate G. This valve H mayeither bevworked from below by pulling upon either end of a cord, I,passing through or over snitableguides and attached either indirectly tothe valve through a lever, J, or directly thereto, as in the case ofother ceiling-ventilators, or it may be operated from the floor above;and to this end the lever J, by which it is actuated, is arranged toproject upward and to a limited extent through or above an aperture inthe register-plate F,.so that by simply touching or moving the upper endof said lever with the foot the valve may be worked as required. Thislever J is fast on a shaft, d, which has its bearings in side strips, KK, fastened at their lower ends to the grate G, and sprung to bear attheir upper ends agains the walls of the box D, which insures the properlocation of the lever and valve; By this arrangement or, combination ofparts the whole working mechanism, including the valve H and grate G,can be readily lifted out, for the purpose of cleaning or dusting them,upon removing the registerplate F, and afterward be as readilyreinserted to their places.

The device also may be used in side walls or partitions, and whetherthus applied or ap plied to ceilings and floors, it presents a neat andornamental appearance, and, used in sitting and other rooms, forms quitean ornamental center-piece. Having thus described my invention, I claimas new and desire to secure by Letters Patent The combination, with theremovable register plate or top F and the air-box D, of the valve H,grate G, and lever J, with its shaft or fulcrum d, all carried by sideor bearing strips arranged to'fit loosely within the box, whereby theworking mechanism and interior parts of the box may be readily insertedto their places and beremoved for the purposes of cleaning whenrequired, essentially as described.
